rear leaf mesurments ???

hey i was just wondering if anyone would have the mesurements for the rear leafs of a 90 3/4 ton 4x4 would be from hole to hole... ?? or if anyone would know if they would work in the back of a 97 yukon ?
Any info would be great .

Ok than , how bout 99 and newer..... any idea what the mesurments are on em..... :screwy: Im tryin to compare

99 and newer , gm went to a longer spring with less leafs. this was to be able to carry the same weight and bive a better ride
